The Willamette River anchors this detailed study of the suburban expansion south of Portland, showing the transition from established neighborhoods like Sellwood and Brooklyn to the growing residential areas around Lake Oswego. The river's character is defined by its islands, including Ross Island and Elk Rock Island, while the western hills are dominated by the heights of Council Crest and Mt Sylvania. Significant educational and medical institutions are concentrated in the north, such as Reed College and the U of O Med Sch complex near the Veterans Hospital. Transportation corridors are well-defined by the Southern Pacific and Portland Traction Co rail lines, alongside the winding Terwilliger Blvd and the Pacific Highway. The southern portion of the map reveals the residential layout surrounding the many bays of Lake Oswego, including Lakewood Bay, punctuated by landmarks like the Oswego Country Club.
